Abstract

Membrane technology plays a vital role in carbon dioxide (CO­2) removal as one of the key actions to mitigate climate change. Additive manufacturing has emerged as an alternative method for membrane fabrication due to its high flexibility. Triply periodic minimal surface (TPMS) architectures are widely recognized for their high mechanical robustness and distinctive properties with continuous smooth geometry and zero mean curvature. These features facilitate seamless fluid flow across the structure, and thus, minimizing stagnant regions and reducing the risk of contamination. Among the TPMS structures, the primitive structure is notable for its high compressive strength and mechanical resistance. This study aims to fabricate and evaluate a primitive-structured zeolitic imidazolate framework-8 (ZIF-8)/polydimethylsiloxane (PDMS) mixed-matrix membrane with 2 × 1 × 1 cubic unit cell for carbon dioxide permeation using a sacrificial mold fabrication approach. The membrane was fabricated using a sacrificial mold printed via fused deposition modeling. The ZIF-8 fillers and membranes were characterized using field emission scanning electron microscopy (FESEM) with energy-dispersive X-ray spectroscopy (EDX), Fourier-transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA). The primitive-structured ZIF-8/PDMS membrane demonstrated CO­2 permeability and CO2/N2 ideal selectivity that are comparable to reported literature values, reaching 13.17 ± 0.57 × 10³ Barrer and 7.76 ± 0.28, respectively, at 0.025 bar. This suggests that removing the sacrificial mold through dissolution is unlikely to compromise the membrane surface, and therefore, represents a viable approach for the fabrication of membranes with complicated structures.
